Drag reduction behavior of hydrolyzed polyacrylamide/xanthan gum mixed polymer solutions

Abstract Partially hydrolyzed polyacrylamide (HPAM) as the main component of slickwater fracturing fluid is a shear-sensitive polymer, which suffers from mechanical degradation at turbulent flow rates. Five different concentrations of HPAM as well as mixtures of polyacrylamide/xanthan gum were prepa...
